            <p>This page documents the interface for the large view of an <a href="../rf-groupterms/#objects-of-symmetry">object of
symmetry</a>. An object of symmetry is
one of <em>Group Explorer&rsquo;s</em> four <a href="../rf-geterms/#visualizers">visualizers</a>, all
of which can appear either in <a href="../rf-um-groupwindow/">group info pages</a>,
<a href="../rf-geterms/#sheets">sheets</a>, or in their own pages. When they appear in
their own pages, this is refered to as a &ldquo;large view,&rdquo; and you can read
about it in general <a href="../rf-um-largewindow/">here</a>. This page covers the
specifics for large views of objects of symmetry.</p>
<p><img alt="A large view of an object of symmetry" src="../illustration-oswindow.png" /></p>
<h2 id="viewing-the-object">Viewing the object</h2>
<p>A symmetry object (unlike multiplication tables and cycle graphs) is a
three-dimensional structure. Thus you can click and drag [one-finger drag]
on the view to rotate it in three-dimensional space; you can right-click and
drag [two-finger drag] to translate it; and you can use the mouse wheel [pinch 
open/close] to zoom in and out. This lets you see all sides of the
object, and seeing it in motion can give you a better mental picture of it.</p>
<h2 id="choosing-which-object-to-view">Choosing which object to view</h2>
<p>Some groups have more than one object of symmetry defined for them. For this
reason, the topmost portion of the control pane on the right side of a large
view for symmetry objecst allows you to choose which of the symmetry objects
you wish to view. You choose from a list, as shown in the picture below.</p>
<p><img alt="Screenshot of the control for choosing an object of symmetry" src="../illustration-osoptions.png" /></p>
<p>In this illustration, the triangle is selected, but the user can click on it
to open a list. Some groups only have one symmetry object on this list, but
others have several. Choosing one changes the view immediately.</p>
<h2 id="related-interfaces">Related interfaces</h2>
<p>The remainder of the controls in the right side of the large window for
symmetry objects are described in <a href="../rf-um-modelview/">the help page for three-dimensional
controls</a>.</p>
